Did you see the link I posted before?The AF101A around € 4000, it is not not ridiculous at all... I just hope that they also revised a little the anti aliasing filter to restore the definition, and pass from 750 to 850 lines ...
http://provideocoalition.com/index.php/awilt/story/ag-af100_and_pmw-f3_on_the_charts/P1/ in case you missed it. Both Adam Wilt and Alan Roberts found the AF100 to have a limiting resolution of only about 680lpph. And Adam publishes a chart that conclusively backs up their statements.
Just look at the horizontal section of that chart, with the trumpet of near horizontal converging lines. If you looked at the real chart you'd see lines converging all the way towards the centre. On the image they start to converge - then start to diverge again. The point at which the change happens corresponds to the limit of true resolution. Where real resolution becomes aliasing. And it's plain that that happens well before 750lpph, if anything, 680lpph is being a bit generous.
As for the anti aliasing filter, it's also clear from those charts that it is not very aggressive. The diverging lines are distinct to well beyond 1000lpph - and that they are diverging means they must be aliases. That they exist at all means that any anti-aliasing filter is not much attenuating detail of 1000lpph and above.
So no chance of tweaking the OLPF to improve real resolution. Without a sensor upgrade, it will be limited to 680lpph at best. That's not just opinion - the chart proves it.
